Steering Question

I have an 06 C6 auto with F55, 7600 miles. Car has no vibration whatsoever at any speed, tires in excellent condition. When driving at highway speeds if I am on a slight curve and there is a bump or imperfection on the road the steering feels hard to control, feels like the steering wheel moves quickly left/right. Low speeds no effect, going straight, no issue. Any ideas as to what I should get checked?

Steering wheel is straight, car goes straight as an arrow. Of course, that does not necessarily mean alignment is to spec...

My 05 got to jumping a little left or right as it crossed pavement seams, truck ruts etc. Alignment corrected several out of spec settings, car drives 100% normal again.

If it's what I'm thinking, its a normal thing that can be cured by replacing the shocks with good ones. I did Bilsteins and they are the best $300 I have spent.

Will have to bring to the dealer. It's a CPO vehicle which would then cover any parts that may need replacing. Alignment would be out of pocket, I assume.

Might be a problem, but there is also some intentional feedback into the steering wheel to provide "feel". That can cause the symptoms you describe, especially if only one front wheel hits the bump; it's a matter of degree. Can you compare it to another C6 with the same suspension and tires?
